Theoretical developments in the SMEFT at dimension-8 and beyond
Simone Alioli, Radja Boughezal, Weiguang Cao +24
In this contribution to the Snowmass 2021 process we review theoretical developments in the Standard Model Effective Field Theory (SMEFT) with a focus on effects at the dimension-8…
On-shell Higgsing for EFTs
Reuven Balkin, Gauthier Durieux, Teppei Kitahara +2
We study the on-shell version of the Higgs mechanism in effective theories (EFTs) containing particles of different spins, focusing on contact terms as a simple starting point. We…
Constructing massive on-shell contact terms
Gauthier Durieux, Teppei Kitahara, Camila S. Machado +2
The purely on-shell approach to effective field theories requires the construction of independent contact terms. Employing the little-group-covariant massive-spinor formalism, we p…
The electroweak effective field theory from on-shell amplitudes
Gauthier Durieux, Teppei Kitahara, Yael Shadmi +1
We apply on-shell methods to the bottom-up construction of electroweak amplitudes, allowing for both renormalizable and non-renormalizable interactions. We use the little-group cov…
Effective Field Theory Amplitudes the On-Shell Way: Scalar and Vector Couplings to Gluons
Yael Shadmi, Yaniv Weiss
We use on-shell methods to calculate tree-level effective field theory (EFT) amplitudes, with no reference to the EFT operators. Lorentz symmetry, unitarity and Bose statistics det…
Tagging new physics with charm
Sho Iwamoto, Gabriel Lee, Yael Shadmi +1
We propose a new variable, the charm fraction, for collider searches for new physics. We analyze this variable in the context of searches for simplified supersymmetry models with s…
